REFRIGERATION
(Self Contained Models)
Each self contained model is equipped with
its own condensing unit and control panel
located beneath the display area. The correct
type of refrigerant will be stamped on each
merchandiser's serial plate. The merchandiser
refrigeration piping is leak tested. The unit is
charged with refrigerant, and shipped from
the factory with all service valves open.
GSVM models have a refrigeration system
that uses a hermetic compressor. GSVM-4060
and GSVM-4072 systems use a capillary tube
for refrigerant control. The capillary tube is
soldered to the suction line pull-out coil for
proper heat exchange. If the capillary should
become plugged or damaged, it is best to replace
the heat exchanger.
GSVM-5272 employs a bleed port type
expansion valve for proper refrigerant control.
Read the merchandiser's serial plate for the
appropriate refrigerant type and weight.
— LOCK OUT / TAG OUT —
To avoid serious injury or death from electri-
cal shock, always disconnect the electrical
power at the main disconnect when servicing
or replacing any electrical component. This
includes, but is not limited to, such items as
doors, lights, fans, heaters, and thermostats.

WATER OUTLET AND WATER SEAL
GSVM models 4072 and 5272 require a floor
drain. The condensate water outlet is located
in the center of the merchandiser. The outlet
has a factory-installed external water seal.
For self contained models like GSVM-4060,
this water seal drains into an electric condensate
pan located beneath the merchandiser. The
pan uses a thermistor that senses water in the
pan, adjusting the amount of heat required
to evaporate the water. Ensure the drain hose
is properly trapped, and the drain area is not
clogged.
For self contained models like GSVM-4072
and GSVM-5272, this water seal drains into
an electric condensate pan located beneath
the merchandiser. The pan uses a thermistor
that senses water in the pan, adjusting the
amount of heat required to evaporate the
water. GSVM has an electric condensate pan
and uses a floating sensor.
Ensure the drain hose is properly trapped,
and the drain area is not clogged. (Review
note)
NOTE: All lower base panels must be in place
when the refrigerator is operating. If not, airflow
from the condenser will be directed over the evap-
orator pan and defrost water in the pan may over-
flow.
OPTIONAL ELECTRIC
CONDENSATE PAN
An optional high-humidity condensate pan
kit requires a dedicated 15 Amp circuit - 120V
(GSVM-4072 and GSVM-5272).
